| <p> |
| Apache Ignite is capable of caching web sessions of all Java Servlet containers that |
| follow Java Servlet 3.0 Specification, including Apache Tomcat, Eclipse Jetty, Oracle WebLogic, and others. |
| </p> |

| <h2>Horizontal Scalability</h2> |
| <p> |
| Ignite Web Sessions Cache is a distributed cache that maintains a copy of all web sessions’ data in memory. |
| In case of an application server failure, web requests get routed to another application server that |
| simply fetches the web session data from Ignite distributed cache. |
| </p> |
| <h2>Fault Tolerance</h2> |
| <p> |
| Ignite ensures fault tolerance by either replicating or partitioning the sessions' data |
| across all cluster nodes. Ignite guarantees that no session is ever lost, providing a |
| better user experience. |
| </p> |
| |
| |
| <h2>No Sticky Sessions</h2> |
| <p> |
| With web session caching, sticky connections become less important as sessions are now available |
| on any application server the web request may be routed to. |
| </p> |
| <h2>Plug-n-Play</h2> |
| <p> |
| Ignite web session clustering automatically plugs into any application server or servlet container. |
